Um...I am not sure about not being able to have both Broadleaf backs. I have never seen one with both AB backs but here is a Phelps with an Olive back. I know for a fact there are at least two different olive ones floating around (one that Patrick Knoll had with a stamped star) and another auctioned a while back without a star stamp.
The Phelps Broadleaf is Olive...see a scan here

Downey is in olive as well...a scan can be found by searching here on net54.
